What Is a Water Leak?

Understanding the Hidden Threat to Your Monte Sereno Home

A water leak occurs when water escapes from your plumbing system through a crack, corroded joint, pinhole, or broken section of pipe. Leaks can develop in any part of your home’s water supply or drainage system — including pressurized water lines, slab-embedded pipes, toilet supply connections, water heater fittings, and outdoor irrigation lines. Some leaks are visible, such as a dripping faucet or a puddle beneath a sink. However, the most damaging leaks are often hidden — running silently behind walls, under flooring, or beneath concrete slab foundations where they can go undetected for weeks or even months.

In Monte Sereno, where many homes were built between the 1950s and 1970s, original plumbing materials like copper and galvanized steel are especially prone to age-related deterioration. Left unaddressed, even a small pinhole leak can waste thousands of gallons of water per year, cause wood rot in structural framing, and create conditions for toxic mold. That’s why early water leak detection is critical to protecting both your home and your health.

Did You Know

A single leak dripping at one drop per second wastes approximately 3,000 gallons of water per year. According to the U.S. Environmental Protection Agency, the average American household loses more than 10,000 gallons annually to plumbing leaks — enough to fill a backyard swimming pool. For Monte Sereno homeowners on San Jose Water Company metered billing, that wasted water translates directly into higher utility costs and unnecessary strain on California’s already limited water resources.

Unexplained spike in your water bill

Unexplained increase in your water bill — A sudden spike without a change in usage is one of the most reliable indicators of a hidden leak.

Sound of running water when all fixtures are off

Sound of running water when all fixtures are off — If you hear water flowing through pipes when nothing is in use, a leak is likely present.

Warm or hot spots on your floor

Warm or damp spots on floors — Especially on concrete slab foundations, warm patches may indicate a hot water slab leak beneath your home.

Damp, soft, or discolored spots on walls, ceilings, or floors

Water stains, bubbling paint, or warped flooring often signal a leak behind the surface.

Musty or mildew odors

Mold, mildew, or musty odors — Persistent moisture behind walls or under flooring creates the perfect environment for mold growth.

Unusually lush or soggy patches in your yard

Wet or soggy patches in your yard — Unexplained green patches or standing water in your landscape may signal an underground pipe leak.

Low water pressure

Low water pressure — A leak in your main water line can reduce pressure throughout the house.

Cracks in your foundation or flooring

Prolonged slab leaks can erode the soil beneath your foundation, leading to shifting and cracking.

Signs You May Have a Hidden Water Leak in Your Monte Sereno Home

Not every leak announces itself with a puddle on the floor. Many water leaks in Monte Sereno homes remain hidden for long periods. Here are the warning signs every homeowner should watch for.

Pro Tip: Walk through your home once a month and inspect under sinks, around water heaters, and along exposed pipes for signs of moisture. Catching a leak early can save you thousands in repair costs. If you notice any of these signs, contact Drain & Water immediately for a professional leak inspection.

What Monte Sereno Homeowners Say About Drain & Water

The team at Drain & Water crawled under and around our home to find the water leak that ran up our water bill. Leak was detected under our backyard hardscape. The team trenched a replacement pipe to avoid tearing up our hardscape. They did an excellent job of finding the best underground route to lay the pipe. Very happy with the work they did. They are now my go-to team for any plumbing related problems.

Common Leak Detection Technologies We Use

Professional leak detection goes far beyond guesswork. At Drain & Water, we use a combination of industry-leading technologies to accurately locate leaks without unnecessary demolition:

Acoustic Leak Detection

Electronic amplification equipment detects the sound of water escaping from pressurized pipes, even through concrete, soil, and walls. This is one of the most effective tools for locating slab leaks and underground water line breaks.

Thermal Imaging (Infrared Cameras)

Infrared technology reveals temperature variations behind walls and beneath floors, allowing us to identify hot water leaks and moisture accumulation that isn’t visible to the naked eye.

Video Camera Inspection

A high-resolution camera is inserted into drain and sewer lines to visually inspect the interior condition of pipes, pinpointing cracks, corrosion, root intrusion, and joint failures. We offer free camera inspections with qualifying services.

Pressure Testing

We isolate sections of your plumbing system and apply controlled pressure to identify drops that confirm the location and severity of a leak.

Moisture Meters

These handheld devices measure moisture levels in drywall, wood, and concrete to determine the extent of water damage and confirm the presence of hidden leaks.

Line Tracing & Locating Equipment

Electronic pipe locators trace the exact path of underground and in-wall plumbing lines, ensuring we know where pipes run before beginning any repair work.

Pro Tip: Non-invasive detection technology means we can often pinpoint your leak without cutting into walls or jackhammering your slab. Ask about our diagnostic process when you call.
